Igloo v.1.1.1

This release fixes the following issues:

• There was a problem building on some systems due to a missing #include <iterator>
• Context names were not locally scoped. This prevented us from having contexts with the same name but with different parent contexts. (#10)

Igloo v.1.1.0

Adds the following features:

Running single contexts or specs

Appending "_Only" at the end of "Context/Spec", "Describe/It", or "When/Then" will cause Igloo to only run those tests.

Skipping tests

Appending "_Skip" at the end of "Context/Spec", "Describe/It", or "When/Then" will cause Igloo to skip those tests.

Direct access to root context

When having nested contexts it is now possible to access the root context directly using the "Root()" method. With multiple levels of nesting this is a lot simpler than chaining together "Parent().Parent()" until the root context is reached.
